HORSESHOE-CALK.

SPECIFICATION forming part of Letters Patent No. 645,602, dated March20,1900.

Application filed June 7,1899. Serial No. 719,698 (No model.)

To all whom, it may concern:

Be it known that I, JOHN WALLACE MIL- LER, a citizen of the UnitedStates, residing in Muhlenberg, (Bernharts P. O. in the county of Berksand State of Pennsylvania, have invented a new and usefulI-Iorseshoe-Oalk, of which the following is a specification.

The invention relates to improvements in horseshoe-calks.

The object of the present invention is to I improve the construction ofhorseshoe-calks and to provide a simple, inexpensive, and efficientdevice capable of enabling a calk to be readily applied to a horseshoeand adapted when the same becomes worn to permitit to be removed fromthe horseshoe without removing the latter from the hoof of a horse.

The invention consists in the construction and novel'combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of ahorseshoe providedwith toe and heel calks constructed in accordance with this invention.Fig. 2 is a transverse sectional view. Fig. 3 is a detail perspectiveview of one of the split sleeves. Fig. 4 is a detail perspective view ofthe calk.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a horseshoe provided with toe and heel calks 2 and 3, whichare pointed to prevent an animal from slipping on smooth surfaces anddesigned to be used in winter when snow mashes on the ground; butinstead of employing pointed calks, as illustrated in the accompanyingdrawings, it will be readily apparent that blunt calks may be used. Eachcalk is provided with a round shank4, which is of less diameter than thebase ofits conical portion or head, to provide an annular shoulder 5,which is adapted to form astop to pre- Vent the calk from being forcedthrough the shoe against the hoof of an animal.

The shank of the calk is secured within an opening 6 of the horseshoe bya split sleeve 7, provided with a cylindrical bore or opening to receivethe shank 4. The opening 6 of the horseshoe is slightly tapered, asclearlyillustrated in Fig. 2 of the accompanying drawings, and the outerface 8 of the split sleeve is correspondingly tapered, and when it isdriven into the hole of the horseshoe it is compressed and caused toclamp the shank,whereby the calk is securely held in place. The splitsleeve is provided at its outer or lower end with a flange 9, having aboss 10 at itsinner face and provided with oppositely-disposed straightedges 11, forming a wrenchseat, and it is adapted to be readily workedloose by a wrench. The boss 10, which is formed by thickening the innerportion of the flange, offsetsthe flange from the face of the horseshoe,and thereby enables it to be readily engaged by a wrench or other tool.

The edges of the flange 9 are rounded between the straight portions11,:and the device is driven into the opening 6 of a horseshoe by a hammer or other suitable tool. The flange 9, by extending beyond the calk,is adapted to be placed on a suitable anvil or support, and theicalk maythen be driven out of the sleeve by a punch or plunger.

The invention has the following advantages: The calk, which is simpleand compara tively inexpensive in construction, is strong and durable,and itisdetachably mounted on the horseshoe and may be readily removedtherefrom when it is desired to renew it or to change a sharp or pointedcalk for a blunt one.

The tapering sleeve engages the tapered opento without departing fromthe spirit or sacrificing any of the advantages of this invention.

WVhat is claimed is 1. In a device of the class described, thecombination of a horseshoe havinga smooth tapered opening, a calk havinga round shank and having a shoulder, and asplit compressible sleevehaving smooth inner and outer faces and provided with a cylindrical boreor opening for the reception of the shank of the oalk, said sleeve beingexteriorly tapered to be driven into the tapering opening of thehorseshoe and capable of being readily removed therefrom withoutdetaching the said shoe, substantially as described.

2. Ina device of the class described, the

combination of a horseshoe having a tapered.

opening, a calk consisting of a head and a shank of less diameter thanthe head, anda split compressible sleeve having smooth inner and outerfaces and receiving the said shank and being exteriorlytapered to engagethe opening of the horseshoe, said sleeve being provided with a flange 9projecting beyond the calk and having a boss at its inner x5
